  1. CVE-2026-109936 7.5 Élevée

    Unknown Otter Blocks

    The Otter Blocks WordPress plugin before 3.2.8 does not correctly bound a pattern it uses to rewrite its dynamic-content tokens while rendering blocks, so the pattern can consume the quote that closes an HTML attribute and pull adjacent unescaped data into the markup as new attributes. This allows unauthenticated users to achieve stored Cross-Site Scripting that executes in the browser of any visitor who views an affected page, including a logged-in administrator.

  2. CVE-2026-109935 5.3 Moyenne

    Unknown Otter Blocks

    The Otter Blocks WordPress plugin before 3.2.8 does not enforce its block visibility conditions when a published post is rendered through the WordPress REST API, allowing unauthenticated users to read block content that the site owner restricted to specific roles, logged-in users, the post author, categories or tags, or (on the Pro tier) Stripe purchasers.

  3. CVE-2026-109934 5.3 Moyenne

    Unknown Otter Blocks

    The Otter Blocks WordPress plugin before 3.2.8 does not correctly determine whether a post is publicly readable before returning its data through a REST API endpoint, treating any post with the published status as public, allowing unauthenticated users to read manual excerpts of password-protected posts, the content and titles of non-public post types, and, on WooCommerce sites, coupon codes and their descriptions.

  4. CVE-2026-109933 6.8 Moyenne

    Unknown Otter Blocks

    The Otter Blocks WordPress plugin before 3.2.8 does not properly sanitize and escape user-supplied block styling values before writing them into an inline stylesheet, allowing users with contributor-level access and above to inject arbitrary web scripts that execute when any visitor, including administrators, views the affected post.

  5. CVE-2026-109937 5.4 Moyenne

    Unknown Otter Blocks

    The Otter Blocks WordPress plugin before 3.2.3 does not validate that a user-supplied return URL belongs to the site before using it to build the return destination of a Stripe Checkout session, allowing unauthenticated attackers to redirect victims who complete or cancel checkout to an arbitrary external URL.
